From his debut in a six-page comic in 1939 and to his most recent portrayal by Christian Bale in the blockbuster 'The Dark Knight Rises', Batman is perhaps the world’s most popular superhero. The continued relevance of the caped crusader could be attributed to his complex character, his dual identity or his commitment to revenge and justice. But, as the contributors to this collection argue, it is the fans who, with the patience of Alfred, the loyalty of Commissioner Gordon and the unbridled enthusiasm of Robin, have kept Batman at the forefront of popular culture for more than seven decades. 'Fan Phenomena: Batman' explores the unlikely devotion to the Dark Knight, from his inauspicious beginnings on the comic book page to the cult television series of the 1960s and on to critically acclaimed films and video games of today. Considering everything from convention cosplay to fan fiction that imagines Joker as a romantic lead, the essays here acknowledge and celebrate fan responses that go far beyond the scope of the source material. And, the contributors contend, despite occasional dips in popularity, Batman’s sustained presence in popular culture for more than seventy years is thanks in no small part to his fans’ ardour.
